Natural arch

History

Because of its distinctive shape, the arch was known as "the Chaps" and "the Schoolmarm's Bloomers" by local cowboys. It was given its current name by Frank Beckwith, leader of the Arches National Monument Scientific Expedition, who explored the area in the winter of 1933–1934.

 and eventual destruction. The idea was ultimately abandoned as impractical and contrary to NPS principles.

The Delicate arch is reachable by heading into a small pickup trail down the entrance path entering the park.

Geology

Delicate Arch is formed of Entrada Sandstone

. The original sandstone fin was gradually worn away by weathering and erosion, leaving the arch. Other arches in the park were formed the same way but due to placement and less dramatic shape are not as famous.

Hiking to the Arch

Delicate Arch is located at the end of a moderately strenuous, 1.5 mi (2.4 km) hiking trail from the parking area at Wolfe Ranch

The Wolfe Ranch, also known as Turnbow Cabin, is located in Arches National Park near Moab, Utah, U.S.John Wesley Wolfe settled in the location in 1888 with his oldest son Fred. A nagging leg injury from the Civil War prompted Wolf to move west from Ohio, looking for a drier climate...

. Taking thirty to forty-five minutes each way, the round trip is slightly more than 3 mi (4.8 km) long and the Arch is completely hidden from view on most of this trail.

The first third of the hike is through rugged, brushy terrain and gains slightly in elevation. The middle third of the hike is along the face of an exposed slickrock outcrop and is strenuous due to the gain in elevation, but offers better views of the geology

.
The latter third of the trail is the most rugged, nearing the top of the plateau. The Arch is not yet visible, and the trail runs around outcrops, through washes and between stands of twisted brush and trees. The trail may be easier to follow, but meanders as parts become muddy and difficult to walk through. During the 2004 fall season, the trail clearly followed the left (northern) side of the plateau, and brought visitors along a narrow shelf nearly 150 ft (45.7 m) above a dry wash.

The arch comes into view suddenly around a corner in the trail and frames the La Sal Mountains

Controversy

Nature photographer Michael Fatali started a fire under the arch in September 2000 to demonstrate nighttime photography techniques to a group of amateur photographers.

 made the first recorded free solo (no ropes or protection) ascent of this formation. Climbing Delicate Arch was not explicitly forbidden under the rules in force at the time. It was understood, however, that the named-arch formations should not be climbed. The Park Service has since closed the loophole by disallowing climbs on any named arch within the park year-round.

Top-rope climbing is a style in climbing in which a rope, used for the climber's safety, runs from a belayer at the foot of a route through one or more carabiners connected to an anchor system at the top of the route and back down to the climber, usually attaching to the climber by means of a...

. Potter has stated on several occasions that he never top-roped the Arch and no photos exist of Potter using a top rope setup on the Arch. It is possible that a previous climber had top-roped the Arch leaving the rope scars.
